ALFRED E. WOLFF, `OF KANSAS CITY, MSSOURI 'VALVE Application filed December 10, 1927. Serial No. 239,061.

This invention relates to valves for control- 9 is a removable valve seat l2 against which ling the passage of fluids, such as, steam r the ball valve 11 may Contact to prevent the water gas, air or oil and other materials, ball valve from passing from the valve housthrough pipes, the primary object of the ining when the pressure within the valve body a removable inner valve housing in which an The reference character 13 indicates thereautomatically controlled ball valve is held, to movable head forming a part of the valve, the the end that the main valve of the device may head being provided with internal threads to be removed to replace worn partsA thereof accommodate the threaded portion 14 of the i0 without the necessity of cutting off the water valve stem l5.

59 At the opposite end of the valve housing The upper end of the valve housing 34 100 constitutes a seat for the valve member 36 Which valve member carries the pin 37 designed to engage the ball valve 35 to hold the ball valve against the pressure of the inflowing liquid to prevent the liquid from passing through the valve body.

In this form of the invention it Will also be seen that a person may by removing the valve proper, readily repair the same, the pressure of the fluid acting against the ball valve to cause the same `to seat and prevent the passage of Water through the valve body While repairs are being made.

After repairs have been made and the main valve has again been positioned, the pin 37 Will act to force the ball valve 35 from its seat, allovving the iiuid to againfpass through the valve body.

I claim as my invention:

1. A vvalve of the class described including a body portion having an inlet opening and an outlet opening, a removable ball valve housing Within the valve body and having an internal valve seat, a ball valve in the valve housing and adapted to Contact with the internal valve seat to restrict the passage of liquid through the valve body, a manually controlled removable main valve and auxiliary valve operating in the valve body and adapted to engage one end of the valve housing, and means for substituting the auxiliary valve for the main valve.

2. A valve assembly of the class described including a valve body having an inlet opening and an outlet opening, a ball valve housing removably supported Within the valve body and having an internal valve seat, a ball valve operating Within the valve housing, a main valve adapted to engage one end of the valve housing to restrict the passage of liquid through the valve body, means disconnected from the ballvalve and movable Within the valve body for contacting With the ball valve to unseat the ball valve, and means for removing the main valve Without interfering With the function of the valve assembly.

3. A valve of the class described including avalve body, a removable valve housing supported Within the valve body, said valve Y housing having a valve seat formed internally Y thereof, and a valve seat formed externally thereof, a ball valve Within the valve housing and adapted to contact With the internal valve seat to cut off the supply of liquid through the valve body, and a removable main valve adapted to engage the external valve seatv to control the passage of fluid through' the body portion, and a manually operated third valve adapted to replace the removable main valve.

4. A valve of the class described including a valve body having internal threads, a removable valve housing having a threaded portion cooperating With the internal threads valve.
